I have a semi decent PC that can run steam and my games fine on windows, but in Linux, either steam for linux or through WINE, the entire client is laggy and most games run decently but get a few drops (though I'm guessing thats mostly normal)

Any tips on how I can stop the client from being pretty bad performing?

I'm actually having the same problem although my pc is a bit lower end graphics wise I have an old intel chipset 4 from 2010 and when I try to run games namely killing floor and just cause both of which I could run on the highest settings when I was using windows now run at less than 10 fps and some games war off the human tanks and sakura trick won't run at all

CPU: AMD 6100 (its not great but ran games on windwos fine)GPU: AMD 7850running latest linux mint, using the fglrx-updates drivers

the iag is most noticeable in steam chat, trying to type to people and scroll through etc, rest of the client is pretty much okay (in WINE its almost everything that's bad) and in games it's mostly stable but in TF2 for instance i get a few drops and stutters and freezes every now and then, seems inconsistent
